Title:
新規なポリペプチドおよびその製造方法
Document Type and Number:
Japanese Patent JP5070442
Kind Code:
B2
Abstract:
A process for producing a novel polypeptide, which comprises reacting a peptide component (A) represented by the following formula (1a) with a peptide componant (B) represented by the following formula (2a) and a compound (C) represented by the following formula (3a), as an optional component: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ X-(Pro-Y-Gly) n -OH€ƒ€ƒ€ƒ€ƒ€ƒ(1a) wherein "X" represents H or the group HOOC-(CH 2 ) m -CO-, ("m" denotes an integer of 1 to 18), "Y" represents Pro or Hyp, and "n" denotes an integer of 1 to 20, €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ X-(Z) r -OH€ƒ€ƒ€ƒ€ƒ€ƒ(2a) wherein "X" represents H or the group HOOC-(CH 2 ) m -CO-("m" denotes an integer of 1 to 18), "Z" represents a peptide chain comprising 1 to 10 amino acid residue(s), and "r" denotes an integer of 1 to 20, €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ H 2 N-R-NH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(3a) wherein "R" represents a linear or branched alkylene group, wherein the ratio of the peptide component (A) relative to the peptide component (B) [the former (A)/the latter (B)] is 100/0 to 30/70 (mol%); provided that in the case where "X" represents the group HOOC-(CH 2 ) m -CO-("m" has the same meaning as defined above) in the formula (1a) and/or (2a), the amount of the compound (C) is substantially 1 mol relative to 1 mol of the total molar amount of the peptide component (A) and/or the peptide component (B); and in the case where "X" represents H in the formula (1a) and/or (2a), the reaction is conducted without the compound (C). The present invention provides a collagenous polypeptide which is free from a risk of an infection by a pathogenic organism (or a causative factor) or anundesirable side effect, and which has a high safety.
